<p class="purpose">All the built-in adjectives on Basic Inform, from even and odd (for numbers) to symmetric (for relations).</p>

<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. </b>See test case <span class="extract"><span class="extract-syntax">BIP-Adjectives</span></span>.
</p>

<p class="commentary">Something to watch out for here is that the domain of an adjective with an
intentionally broad kind has to be written in a way which considers covariance
and contravariance. Thus, "list of values" matches every list, because "list of K"
is covariant: but "activity on values" does not match every activity, because
"activity on K" is contravariant, and instead "activity on nothing" is needed.
